Hi Craig,
The scan could be started by someone on the Inet, whether you have or not a 
static IP. It always happens.
The default port of Squid is 3128. Its interesting to put your firewall to 
log these not allowed connections, so you'll see from where these 
connections are generated. 
The portscanning is the first action to a possible attack... Portscanning 
let the intruder know something more about your system... If you have some 
dangerous process running on any port, the portscan will show that, unless 
its blocked by your firewall. So the intruder has the capability to DoS or 
penetrating your system.

Hello Everyone.  I'v been noticeing in my snort logs a lot of Squid Proxy 
attemts.  My box is setup as a firewall/gateway for one of my friends but i 
dont think that hes causing them (unless hes capable of spoofing what NIC 
they come in on)I was wondering what could be causing the scans?  and what 
port Squid proxy uses?  And also what kind of danger do these scans present 
to the secruity of my computer?  
Thanks
Craig
